New York is taking one of the country's best-known prediction markets to court. Governor Kathy Hochul and Attorney General Letitia James announced that the state has sued online betting platform Kalshi.
The legal action rests on how the state defines what Kalshi does. An Attorney General's office investigation found that Kalshi's prediction market is an illegal, unlicensed gambling operation.
Officials framed the case as a matter of consumer protection. They said the app exposes New Yorkers, including those under the legal gambling age of 21, to serious personal and financial risk.
At the heart of the dispute is how the platform works. On Kalshi, people trade based on the predicted outcomes of sports, entertainment and even elections, a model the state argues amounts to betting.
The lawsuit's first goal is to shut the operation down in New York. It aims to stop Kalshi from operating an unlicensed gambling business in the state.
It also seeks to claw back money and penalize the company. The suit asks the court to make Kalshi forfeit all illegal gains, distribute restitution to customers, and pay fines equal to three times the amount it made on those gains.
Kalshi is not backing down. The company released a statement calling the lawsuit political theater and arguing that states cannot shut down a federally licensed exchange, setting up a fight over who has the authority to police prediction markets.
